SPECIFICATION forming part of Letters Patent No. 505,889, dated October3, 1893.

Application tiled December 1, 1892. Serial No. 453,744. (No model.)

To all whom t may concern:

Be it known that I, GEORGE W. STROUD, of Chicago, Illinois, haveinvented certain new and useful Improvements in Window-Frames, of whichthe following is hereby declared to be a full, clear, and exactdescription, sufficient to enable others skilled in the art to make anduse the same.

The invention designs to provide a window frame of peculiar structurewhereby the sash can be taken out or replaced as desired, without theneed of removing or disturbing any of the usual frame-parts, such forexample as the inside or outside stops. In preferred form, the stopsreferred to may remain permanently affixed in place; provision beingmade for shifting a section of one of the stiles and parting strip intothe side-box of the frame so that clearing space is afforded sufficientto allow the sash or sashes in turn to be lifted out and away from theirposition on the frame or be returned thereto, as desired.

The exact nature of the improvements will appear from the descriptionand be pointed out by claim at its conclusion.

Figure l is a cross-sectional view of the improved window-frame showingthe position of the lower sash before removal. Fig. 2 is a like viewshowing the position of the upper sash in course of removal. Fig. 3 is aview of the frame with the sashes in position; Fig. 4 a detail View atthe front face of the frame side-box; Fig. 5 a perspective View of themovable section of the pulley-stile and parting strip.

The improved window-frame is constructed for the most part in usualfashion and in the form shown is furnished at its sides with boxessufficiently large to receive the weights which serve as a counter-poisefor the shifting window sashes. The box A consists of the familiar blindstop a and inside casing b extending from top to bottom at the sides ofthe frame. Between these parts at the front are mounted thepulley-Stiles c and the parting-strips d which latter serve as usual toguide and retain the separate sashes at one side of the frame. Thepulley-stile instead of being continuous from top to bottom is dividedtransversely together with the intermediate parting-strip into twosections, one

of whichis fixed to the frame `and the other movable, the latter beingsustained byhinges or like expedient so as to retreat when desired intothe box A. A Y For convenient removal of both sashes the retreatingsection referred to is ordinarily arranged as shown by Figs. 3 and 4 atthelower inner face of the frame side box and consists of the stile chaving the parting-strip d fastened thereto in part at the edge of the stile but with its upper end free so as to yield slightly when pressed bythe thumb. The movable section referred to is secured through the hingese to the companion fixed stile and in such fashion that when the movablesection is in place it constitutes with the fixed part a continuousguide-Way for the sashes from top to bottom of the frame. For snugnessof lit, the joint f between the two sections is generally cut upon abevel and a mortise bolt g carried by the retreating section projectsinto the inside casing b and thus holds the section snugly in place.Said section must be slightly longer than the largest sash which it isdesired to take out or toset in placeand acts somewhat as a gate toadmlt for clearance and passage of the sash when the latter is turnedslantwise for the purpose. Ordinarily the retreating stile section orgate, will be in yposition shown by full ligues, Fig. 1, and in suchrelation will act the same as if the stile were of the usual stationarykind. To remove the inside or lower sash it is first raised to itstopmost limit in the frame, the bolt g Withdrawn and the free end of theparting-strip d pushed inward until itstands iiush with the front faceof the stile section to which it is joined in such position; the stop d'clears the lower edge of the up-lifted sash, then adjacent thereto andturns with the stile c about the hinges e into the box A. The sash B canthen be lowered toits usual place and by sidewise pull and thrust, beremoved from the frame (see dotted lines Fig. l) the stile sectionhaving retreated wholly within the box and oering no impediment to thisshifting movement since the section is then located as displayed by Fig.1 (dotted lines). To remove the upper sash C,itv is merely necessarythat the same be lowered to position ordinarily occupied by thecompanion sash B IOO and then be pulled forward slantwise (Fig. 2), thusclearing the space ordinarily occupied by the stile section and beingultimately withdrawn from the frame.

Obviously, the gate like section can be set in the upper instead of thelower part of the window frame or be arranged at the outerinstead of theinner side of the vertical stile. It is merely necessary that themovable section be long enough to afford clearance for the longest sashwhich is to be taken out or set into place. Where these sashes aremounted without an intermediate Weight, the Window frame should be ttedwith side boxes sufliciently large to receive the retreating stil'esection. It is clear that devices other-Ethan hinges can be used forsustaining the movable section and yet permit its shifting to beaccomplished. y

Modifications in structure can be made according to the skill of themechanic without departing from the spirit of the invention.

Having thus described my invention, what I claim as new,and desire tosecurebyLetters Patent, is-

The combination with the sash, of the sidey GEORGE W. STROUD. Witnesses:
